Skinflint Sunday: Make use of what’s hanging around the house. (Freezer Worm Farm.)

P1010138
Tucked away behind the water tank where you can’t see it from the house is the Freezer Worm Farm! It’s finished!!

Dad turned up today to do the last few steps.

Rather than use new wire mesh over the gravel, I liked the idea of using the old shelves that came in the freezer. Poor Dad had to hacksaw the ends off to get them to fit in the freezer properly, but it worked like a charm. Incidentally, Dad salvaged the bricks that the freezer is propped up on when a house two doors up from my parents was demolished.

A week ago I took Evan15, his friend Louise who is a-girl-but-not-a-girlfriend and 4 sturdy tubs to the soil place where I bought the horrible ph10 compost. We filled up the tubs and we got enough gravel to cover the bottom of the worm farm for $5. Bargain!

The gravel is for drainage. The worm farm is tilted at a slight angle so the worm wee will drain through the ‘floor’ of geotextile (left over from when I put the wicking beds together) and then it runs to this pipe with holes drilled into it. The worm wee then runs down into a strategically placed bucket, to be diluted and fed to my plants. Just realised that the pipe is a leftover from when Mick put the water tank in for me. I think the only things we had to buy for this project was a tube of silicon and the gravel.
(Plus a $1500 replacement freezer… but let’s not talk about that.)

When Dad put the pipe in he also attached a couple of blocks of wood to the door to stop it closing properly, so that it could let in air for the worms and also any hide-and-seeking kids who are stupid enough to try and hide in a worm farm will be able to get out and not suffocate.

A work in progress shot of the geotextile being laid down. In the original worm farm, he used shadecloth, but seeing as I had the geotextile lying around I decided to go with this instead. It’s strong enough to stop tree roots, so it should be strong enough for worms, surely…?

Silicon around the outside of the geotextile to hold it in place, then in a day we’ll be good to go. Shane gave me a bucketful of worms a couple of weeks ago so most of them will move from my ordinary little worm farm into this deluxe mansion and then my plants will be well fertilised for years to come.

Thanks Dad.

    WOW! That is such a great idea for a worm farm! I remember seeing them do it on Gardening Australia last year and thought it was a great re use of a freezer, AND the worms are nice and insulated!
    Keep us posted on how it goes!

    It’s a great feeling to make totally new stuff from old leftovers.
    Kind of like soup from leftover chicken carcasses.

    What a brilliant idea for deluxe worm accommodation. You are going to have just masses of wonderful worm wee! I saw vaguely similar one made out of an old bathtub once. I would kick myself for not thinking of making a worm mansion out of the big old bathtub left over from renos, except I do like the raspberries growing in it instead 🙂

    Looks great! Good comment about the benefit of the insulation. The black plastic worm farms they sell are a stupid idea in hot summers. I lost all my worms a couple of years ago, even though they were in shade. With ambient temperatures in the 40’s, shade is meaningless.

    I ended up putting them under the house where it’s cooler.

  5. That looks so good. I’m really impressed. I hope the worms like their new home and multiply. That’s going to be a lot of wee!

    That looks great. It should last for decades!!

  7. L says:

    That really is the Taj Mahal for worms!

  8. Yay – it looks great. I too thought of the insulation qualities of the ex-freezer given the extremes that Melbourne’s temps can reach (both high and low).

    What a great way to get happy, hungry productive worms. Oh – and its all dog and chook proof.

    Cat or son proof is another matter!!!

    How is the worm farm going now , and did you have to get the freezer degassed before using it ?

Don't be shy... say something!
